Go with a Patterned Shirt
A subtle plaid looks great on its own, with a jacket, or layered under a sweater. Shirt ($345) by Ermenegildo Zegna.

Get a Navy Suit
This three-season wool two-button is a multipurpose workhorse on the road. Wear it as a full suit or pair the pants with a cardigan or the jacket with jeans—you can't go wrong. Suit ($1,980) by Prada.

Choose a Versatile Shoe
These elegant double-monks go
with anything, and the straps are a
hell of a lot more TSA-friendly than laces. Shoes ($345) by Allen Edmonds.

Try a Neutral Tie
Dark, understated options will sync with any shirt you pack, regardless of color
or pattern. Tie ($140) by Alexander Olch.

Stay Secure With Sturdy Luggage
Unlike a typical soft wheelie, a hard case lets you pack even your most precious cargo without worry. Get one in durable polycarbonate for the most protection. Trunk ($475) by Rimowa.

Just because you're living out of a suitcase doesn't mean you can't take care of your garments. Pack two TSA-friendly items—a 3 ounce version of Downy Wrinkle Releaser and a mini lint roller—to keep your clothes both smooth and clean. And once your trip's done, keep your dirty clothes separate from the fresh ones with the Tide odor-absorbing laundry bag. Sure, they might not be as essential to your trip as, say, your boarding pass and passport—but they're pretty damn close.
